What bulb combo is best?

[sphelps]

If you have the ability to run only two bulbs while the remaining stay off then the 2 actinics may be worth while, otherwise they will just get drowned out.

This my vote:

BACK
12-15K (Blue special or similar)
22K (blue + or whatever)
FIJI Purple or similar
12-15K (Blue special or similar)
22K (blue + or whatever)
12-15K (Blue special or similar)
FIJI Purple or similar
22K (blue + or whatever)
12-15K (Blue special or similar)
22K (blue + or whatever)
FRONT

Personally wouldn't bother with 10K or daylight bulbs. Keep things fairly simple to begin with and experiment with new bulbs as time goes on.
